How I teach this to the kids . . .
We stand on one leg. Wave our arms. Point down at our leg and we yell -- Independent!
Then we stand on the other leg. Wave our arms. Point down at our leg and we yell -- Independent!
Then we jump up and down, jog in place, and dance around. Point down at both our legs and we yell -- Inter-dependent! Working Together!
THEN. We stand, cross our legs left and right, all tangled together. Wave our arms and fall down -- yelling Co-Dependent!
We all get up laughing.
Even the 5 year old understands this.
